We report on wavelength-sized GaAs optomechanical disk resonators showing ultra-strong optomechanical interaction. We observe optical transduction of a disk mechanical breathing mode with 1.4 GHz frequency and effective mass of ~ 2 pg. The measured vacuum optomechanical coupling rate reaches g 0 = 0.8 MHz, with a related differential optomechanical coupling factor g om = 485 GHz/nm. The disk Brownian motion is optically resolved with a sensitivity of 10 -17 m/√Hz at room temperature and pressure.Optomechanical systems 1-3 combining a mechanical oscillator and an optical cavity find now applications in very different fields of physics, from mesoscopic quantum physics to cold atoms 4-5 and mechanical sensing 6 . GHz mechanical oscillators can help accessing the quantum regime of optomechanics, can allow developing ultra-fast sensing systems, or can match hyperfine transitions of (artificial) atoms interfaced with the mechanical system. The difficulty lies generally in coupling such GHz oscillators to photons efficiently, in order to offer optical control over the oscillator motion, together with fine optical read-out sensitivity. 7 A useful way a)

“…22,38 Alternative heat sources include a focused CO 2 laser, which is scanned along the fiber [39][40][41][42][43] or a stationary CO 2 laser focused onto the fiber via a diffractive optical element. 44 Microfurnaces in the form of electric strip heaters, [45][46][47][48][49] and sapphire tubes 50,51 have also been used. In the case of sapphire tubes, the tube is heated using a CO 2 laser.…”

We review the method of producing adiabatic optical micro-and nanofibers using a hydrogen/oxygen flame brushing technique. The flame is scanned along the fiber, which is being simultaneously stretched by two translation stages. The tapered fiber fabrication is reproducible and yields highly adiabatic tapers with either exponential or linear profiles. Details regarding the setup of the flame brushing rig and the various parameters used are presented. Information available from the literature is compiled and further details that are necessary to have a functioning pulling rig are included. This should enable the reader to fabricate various taper profiles, while achieving adiabatic transmission of ~ 99% for fundamental mode propagation. Using this rig, transmissions ranging from 85-95% for higher order modes in an optical nanofiber have been obtained.

“…This results to a transmission spectrum with irregular fringes as shown by the dotted graph in Fig. 3 and the excess loss of the tapered fiber is ~0.6dB (Ding et al, 2010;Orucevic et al, 2007 ). This tapered fiber is not suitable to be used in the ensuing fabrication of microfiber devices.…”

“…The increasing deposition of particles (dust) and water molecules on the microfiber is one of the major factors which causes adsorption and scattering of light that lead to perpetual decay in transmission (Ding et al, 2010 ). In an unprotected environment, freestanding microfibers may sway in the air due to the air turbulence.…”
